Currently using enhanced rules, least till I understand whats there. When I uncheck application filtering, windows update (manual) works. When I leave it checked it stops working. I deleted every entry in application filtering, but left it checked, went to windows update, I got 2 popups, I authorized both (explorer/svchost), yet manual updates dont work, instead get this same error [Error number: 0x80072EFD] The website has encountered a problem and cannot display the page you are trying to view. The options provided below might help you solve the problem Works fine as soon as I uncheck application filtering. So its blocking something, but I cant get to it. I found this via search http://www.wilderssecurity.com/showthread.php?t=101792&highlight=windows update defenestration tracked problem to blocked winhttp.dll. I cant find file and add as allow, since not exe, wont let me see it via lns add. Since I only have two entries that I see, both are allowed, are there other entries somewhere? I dont see where dll's are allowed or blocked (assuming thats the problem), am I not seeing a setting somewhere?
